Neural Activity in Quarks Language: Lattice Field Theory for a Network of Real Neurons. [PDF]

open access: yesEntropy (Basel), 2023
Brain–computer interfaces have seen extraordinary surges in developments in recent years, and a significant discrepancy now exists between the abundance of available data and the limited headway made in achieving a unified theoretical framework.

Wavelets and Lattice Field Theory.

open access: yesEPJ Web of Conferences, 2018
When continuous fields are expanded in a wavelet basis, a D-dimensional continuum action becomes a (D+1)-dimensional lattice action on the naively discretized Poincare-patch coordinates of an Euclidean AdS(D+1).

Real-time spin systems from lattice field theory [PDF]

open access: diamondJournal of High Energy Physics, 2023
We construct a lattice field theory method for computing the real-time dynamics of spin systems in a thermal bath. This is done by building on previous work of Takano with Schwinger-Keldysh and functional differentiation techniques. We derive a Schwinger-

Variational structure of Luttinger-Ward formalism and bold diagrammatic expansion for Euclidean lattice field theory. [PDF]

open access: yesProc Natl Acad Sci U S A, 2018
Significance Many-body perturbation theory is one of the pillars of quantum many-body physics and has been used extensively to predict ground-state and excited-state electronic properties of real materials in the past few decades.

An alternative lattice field theory formulation inspired by lattice supersymmetry

open access: yesJournal of High Energy Physics, 2017
We propose an unconventional formulation of lattice field theories which is quite general, although originally motivated by the quest of exact lattice supersymmetry. Two long standing problems have a solution in this context: 1) Each degree of freedom on

Diffusion models as stochastic quantization in lattice field theory [PDF]

open access: yesJournal of High Energy Physics, 2023
In this work, we establish a direct connection between generative diffusion models (DMs) and stochastic quantization (SQ). The DM is realized by approximating the reversal of a stochastic process dictated by the Langevin equation, generating samples from

A Gentle Introduction to Lattice Field Theory [PDF]

open access: yesEntropy
The principles of Lattice Field Theory (LFT), in particular Lattice Gauge Theory (LGT), are explained for a nonspecialist audience. We describe some of the successes of the program; we also discuss the relationship between LFT and Quantum Cellular ...

Towards novel insights in lattice field theory with explainable machine learning [PDF]

open access: hybridPhysical Review D, 2020
Machine learning has the potential to aid our understanding of phase structures in lattice quantum field theories through the statistical analysis of Monte Carlo samples. Available algorithms, in particular those based on deep learning, often demonstrate

RG-inspired machine learning for lattice field theory

open access: yesEPJ Web of Conferences, 2018
Machine learning has been a fast growing field of research in several areas dealing with large datasets. We report recent attempts to use renormalization group (RG) ideas in the context of machine learning.

Holographic mean field theory and Kondo lattice [PDF]

open access: greenJournal of High Energy Physics
We first study a non-relativistic field theory model for the Kondo lattice by introducing the Kondo condensation, whose main effect is the hybridization of the flat band of the localized electron with dispersive one of the itinerant electron. The problem
